One last, last question... Is it worth dodging certain set bonuses (such as crit, maybe even haste?) to gain that extra 160 haste from a yellow gem rather than being forced to use a green/orange?
Okay, let's look specifically at your shoulders and do some math. We're only going to look at one gem for the red socket, since you would obviously use a haste gem in the yellow socket by default. For weight coefficients, we'll say W(s)=1, W(h)=.53, and W(c)=.46 for strength, haste, and crit respectively - made up numbers, but relatively accurate as that's about what I have been seeing in my gear.
So, the difference in haste between a Fierce and a Quick gem is 160, which translates to ~85 strength (160 * .53). Obviously, that's more than the 80 strength you gain from a Fierce gem - but wait! With the orange gem, you match the socket and gain its bonus of 120 crit, which is ~55 (120 * .46). So the real value of the orange gem is 133 (55 + 80), and that more of a gain than the 85 from the pure haste gem.
I don't mean to patronize you, but the simple illustration serves to get the gist across as easily as possible...And that's also how I look at it, in simplest possible terms.
Also... Fail roll protection? What? Why was I not informed of this?
Uses of charm coins that yield gold are supposed to add a stacking increase in the chance to receive loot until such time as a coin yields loot. A somewhat weak attempt to break bad luck streaks, but it's better than nothing.
Thanks a bunch for your time, you're really quite informative.
No prob, man; glad to be of service.
